摘要：
High capacity cellular mobile radiocommunication services in Europe and in North America have set extremely demanding minimization interference targets for the involved operating systems, in order to keep spectrum efficiency in high levels. The evaluation of the conditional cochannel interference probability remains a very interesting scientific area and a major concern in mobile communications. Therefore the evaluation is strongly needed to maintain the required transmission quality level, to control the spectrum efficiency, to optimize the design criteria and to predict the signal-to-interference ratio in different cellular systems. In this paper, a new mathematical method is presented suitable for the exact evaluation of the outage probability of this type of interference under specific considerations concerning the existing mobile's propagation environment. Using this prototype method, a high level of probability's accuracy is obtained especially in the worst cases, where the received signal is degraded due to the presence of radio-shadowing phenomena.
